These days, most people have a smartphone that they check in on every few minutes. The light from your smartphone screen might seem harmless, but in reality, it could be hurting your eyes. Read on to discover the major problem with smartphone screens and how it could be causing long-term damage to your vision that could cause blindness someday.
The Problem With Smartphone Screens
Not all smartphone screens are identical, but they all use very similar methods of projecting light. In order to create the images you see on the screen, different spectrums of light are necessary. This same process is used for computer screens, tablets, televisions, and basically anything else that projects a full-color image on a screen. Unfortunately, that means all of these devices can potentially contribute to vision damage. Just how do they do this? All of them produce blue light, which can be damaging to your eyes.
Blue light is a light spectrum which has been shown to have negative consequences for your eyes. This particular form of light can create eyestrain and stress in the short-term, which is part of the reason why your eyes may feel tired after staring at your phone for a long time. However, the problems don't stop there.
Over time, exposure to blue light can damage the retinas of your eyes. Retinas are what convert the light that enters your eye into an image that your brain can understand, so they're essential for your vision. Blue light can harm the cells of the retina, and eventually, trigger macular degeneration later in life.
What To Do
For most people, putting down the smartphone forever isn't an option. Thankfully, there are some ways you can protect your eyes from your phone without giving up on it.
One of the easiest things you can do for your eyes is to get an eye exam and have an anti-blue light coating added to your next pair of corrective lenses. This will filter out the majority of blue light before it can reach your eyes, protecting you. Best of all, blue light filtering on glasses doesn't create the same kind of color alteration that phone screen filters use.
While you wait for your new corrective lenses, you can use a phone filter. These are apps that are designed to shut off some of the blue light your phone emits. You can set it to completely eliminate blue light or only dial it down a little. Either will help to protect your eyes from cumulative damage, so give them a try.
Your next pair of glasses or contacts can protect your eyes from blue light, but you can take action today to start protecting yourself. Start by making an appointment with your optometrist and then download a blue-filtering app for your phone. For more information on eye exams, contact your local eye doctor today.
